Configuring Graphite on Centos 7

Clone the source code:
git clone https://github.com/graphite-project/graphite-web.git
cd graphite-web
git checkout 0.9.x
cd ..
git clone https://github.com/graphite-project/carbon.git
cd carbon
git checkout 0.9.x
cd ..
git clone https://github.com/graphite-project/whisper.git
cd whisper
git checkout 0.9.x
cd ..

Configure whisper:
pushd whisper
sudo python setup.py install
popd

Configure carbon:
pushd carbon
sudo python setup.py install
popd
pushd /opt/graphite/conf/
sudo cp carbon.conf.example carbon.conf
sudo cp storage-schemas.conf.example storage-schemas.conf
popd

storage-schemas.conf has information about schema definitions for Whisper files. We can define the data retention time under this file. By default it retains everything for one day. Once graphite is configured changing this file wont change whisper’s internal metrics. You can use whisper-resize.py for that.

Configure Graphite
pushd graphite-web
python check-dependencies.py
Install the unmet dependencies:
sudo apt-get install python-cairo python-django python-django-tagging python-memcache python-ldap
python-txamqp
popd

Configure the webapp:
pushd graphite-web
sudo python setup.py install
popd

Configure Graphite webapp using Apache:
Install apache and mod_wsgi:
sudo apt-get install apache2 libapache2-mod-wsgi

Configure graphite virtual host:
sudo cp graphite-web/examples/example-graphite-vhost.conf
/etc/apache2/sites-available/graphite-vhost.conf
sudo ln -s /etc/apache2/sites-available/graphite-vhost.conf /etc/apache2/sites-enabled/graphite-vhost.conf
sudo unlink /etc/apache2/sites-enabled/000-default.conf

Edit /etc/apache2/sites-available/graphite-vhost.conf and add
WSGISocketPrefix /var/run/apache2/wsgi
Edit /etc/apache2/sites-available/graphite-vhost.conf and add
<Directory /opt/graphite/conf/>
Options FollowSymlinks
AllowOverride none
Require all granted
</Directory>
Reload apache configurations:
sudo service apache2 reload

Sync sqlite database for graphite-web:
cp /opt/graphite/webapp/graphite/local_settings.py.example
/opt/graphite/webapp/graphite/local_settings.py
cd /opt/graphite/webapp/graphite
You can add turn on debugging for graphite-web by adding following to local_settings.py:
DEBUG=True
sudo python manage.py syncdb
while doing db-sync you will be asked to create superuser for graphite. Create a superuser and password for it.
Change owner of graphite storage directory to a user through which apache is being run:
sudo chown -R www-data:www-data /opt/graphite/storage/

Configure nginx instead of apache:

Install necessary packages:
sudo apt-get install nginx php5-fpm uwsgi-plugin-python uwsgi
Configure nginx and uwsgi:
cd /opt/graphite/conf/
sudo cp graphite.wsgi.example wsgi.py
Create a file /etc/nginx/sites-available/graphite-vhost.conf and add following to it:
server {
listen 8080;
server_name graphite;
root /opt/graphite/webapp;
error_log /opt/graphite/storage/log/webapp/error.log error;
access_log /opt/graphite/storage/log/webapp/access.log;

location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:3031;
}

}
Enable the nginx server
sudo ln -s /etc/nginx/sites-available/graphite-vhost.conf /etc/nginx/sites-enabled/graphite-vhost.conf
Create a file /etc/uwsgi/apps-available/graphite.ini and add following to it:
[uwsgi]
processes = 2
socket = 127.0.0.1:3031
gid = www-data
uid = www-data
chdir = /opt/graphite/conf
module = wsgi:application
sudo ln -s /etc/uwsgi/apps-available/graphite.ini /etc/uwsgi/apps-enabled/graphite.ini

Restart services:
sudo /etc/init.d/uwsgi restart
sudo /etc/init.d/nginx restart

Start Carbon (the data aggregator):
cd /opt/graphite/
./bin/carbon-cache.py start

 

Access the graphite home page:
Graphite homepage is available at http://<ip-of-graphite-host>

Connect graphite to DSP-Core:

For connecting your DSP-Core with graphite you need to install carbon agnet over your
DSP-Core machine so that carbon agent will send the data to your graphite host which can be
displayed over web-UI. Follow these steps to connect your DSP-Core with graphite.
Install carbon over DSP-Core machine:
git clone https://github.com/graphite-project/carbon.git
cd carbon
git checkout 0.9.x

cd ..
pushd carbon
sudo python setup.py install
popd
pushd /opt/graphite/conf/
sudo cp carbon.conf.example carbon.conf
sudo cp storage-schemas.conf.example storage-schemas.conf

popd
Configure DSP-Core to send data to graphite:
You need to add following to /data1/deploy/dsp/current/dsp-core/conf/bootstrap.json
"carbon-uri": ["<IP-of-graphite-host>:2003"]
